Introduction: Preoperative chemotherapy (CT) and preoperative chemoradiation therapy (CRT) for resectable oesophageal cancer have been shown to improve overall survival in meta-analyses. There are limited data comparing these preoperative therapies. We report the outcomes of a randomised phase II trial comparing preoperative CT and CRT for resectable adenocarcinoma of the oesophagus and gastro-oesophageal junction. Methods: Patients were randomised to receive preoperative CT with cisplatin (80 mg/m2) and infusional 5 fluorouracil (1000 mg/m2/d) on days 1 and 21, or preoperative CRT with the same drugs accompanied by concurrent radiation therapy commencing on day 21 of chemotherapy and the 5 fluorouracil reduced to 800 mg/m2/d. The radiation dose was 35 Gy in 15 fractions over 3 weeks. The endpoints were toxicity, response rates, resection (R) status, progression-free survival (PFS), overall survival (OS) and quality of life. Results: Seventy-five patients were enroled on the study: 36 received preoperative CT and 39 preoperative CRT. Toxicity was similar for CT and CRT. Eight patients (11%) did not proceed to resection. The histopathological response rate (CRT 31% versus CT 8%, p = 0.01) and R1 resection rate (CRT 0% versus CT 11%, p = 0.04) favoured those receiving CRT. The median PFS was 14 and 26 months for CT and CRT respectively (p = 0.37). The median OS was 29 months for CT compared with 32 months for CRT (p = 0.83). Conclusions: Despite no difference in survival, the improvement from preoperative CRT with respect to margin involvement makes this treatment a reasonable option for bulky, locally advanced resectable adenocarcinoma of the oesophagus. © 2010 Elsevier Ltd.
